Re: Fun with Math

that a moot point. they would never consider a non-raid like solution to begin with. i'm 90% sure that servers only use RAID. they aren't stupid enough to only store it on a couple 1TB hard drives with no backups.

also, don't underestimate the speed of high density drives.

I'm not trying to underestimate the speed, but this sort of setup would most likely be stored in a SQL database on an external SAN for large ISPs, and when you are writing THAT many entries the latency difference between 7200RPM and 15000RPM makes a difference. My point is the cost for storage shouldn't be thought of as just being the cost of storing this data on a desktop because all of the extra costs to ensure that it operates safely and smoothly REALLY adds up.
